In this study, the friction and damping values that arise during the deployment of the folded fin mechanism were obtained based on the experimental data. Although there are recommended values for friction in the literature, damping is a phenomenon that varies from system to system and must be obtained through test data. In this study, firstly, the mechanism was operated on the test device with a specific drive pressure and the actual drive pressure generated in the system was measured. The dynamic behaviour of the mechanism was recorded by a High-Speed camera system as well. Adams MBD (multi-body dynamics) was used to define the mechanism model and drive pressure data from the test was defined as input to the model. With the help of Adams DOE (Design of Experiments), certain intervals were defined for friction and damping, multiple analyses were carried out at the friction and damping intervals defined and total deployment time of the mechanism and the dynamic behaviours it exhibited during deployment were obtained. From these numerical results obtained, friction and damping values were obtained based on the model with the highest correlation and test results. The same mechanism was tested for different drive pressures with the specified friction and damping values and the results were compared to the numerical models. It was decided that the friction and damping values determined as a result of the comparison could be used in future numerical analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
